CHARLES NORDSTROM, OF CHICAGO, ILLINOIS.

CREAM-SEPARATOR.

Application filed September 24, 1908.

T 0 all whom it may concern:

Be it known that I, CHARLES NORDSTROM, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Cream-Separators, ofwhich the following is a specification.

This invention relates to centrifugal cream separators, and has for itsobject to provide a construction improved particularly with respect tothe means for assembling and holding the disks upon the bowl and aroundthe feed pipe which is at the center.

A. characteristic feature of the structure is that the bowls are made ofsegmental sections mounted and assembled together upon a rigidstructure, and capable of being readily applied or put in position, andsecurely held by simple devices as hereinafter described.

The invention will be hereinafter more fully described, and anembodiment thereof is illustrated in the accompanying drawings, butchanges in the form, proportion, size, and other details may be madewithin the scope of the invention, which is not limited to theparticular embodiment shown.

In the drawings, Figure 1 is a vertical, central longitudinal section ofthe separator constructed in accordance with the invention. Fig. 2- is atop view, the top of the casing being removed. Fig. 3 is a side viewwith the casing removed. Figs. 4 and 5 are details of a bowl segment anda distributing pipe respectively.

Referring specifically to the drawings, (1 indicates the top of thebowl, I) the feed pipe at the center, and c the shell of the bowl,resting upon the bottom 1 which is supported on the spindle The wholemilk enters at the top through the feed pipe 1) into a bottom cone d,which rests upon the bottom Z of the bowl. The feed pipe I) is screwedinto a hollow socket y formed integral with the bottom Z, and having anoutlet into the chamber within the cone d.

Projecting upwardly from the cone d is a series of distributing pipes e,from which the milk flows in between the bowl segments 71, the creamfinally flowing out at the top through an outlet to in the neck of thecasing, while the skimmed milk escapes through an outlet 2, inconsequence of the centrifugal action, and in a manner well understood.On the bottom cone d is fastened a series of Specification of LettersPatent.

vertical radial wings g, the number of which can be two, three, or more,preferably three. These wings g are connected at the top to a ring athat fits the feed pipe I), and these wings serve to divide or separatethe segments of the disks. The bottom cone is provided with sockets fwhich receive the lower ends of the distributing pipes e which rest onan offset f in the socket, the hole in the bottom of the socket beingmade to correspond with the hole in the distributing pipes 0. Thesepipes are closed at the top and are pointed to fit recesses a in theunder side of the bowl top, as shown. The distributing pipes are arealso slotted as indicated at c, the slots being turned outwardly whenthe pipes are placed in position.

On the pipes e are placed the segments i of the disks, the segmentshaving holes 2" to receive the pipes. Pins Zc are then put through theupper ends of the pipes, so the segments cannot come off.

The complete disks are formed by segments on the respective pipes, andeach pipe 6 with the segments thereon is placed between two of the wingsg, and the pipe c is forced down into the socket f and similarly withthe other parts. Staples h are then placed in position, one on eachwing, the bend of the staple at the top engaging in a notched end on thewing, and the lower end of the staple being ressed into holes h 011 theouter rim of t e bottom cone. The notch m on the wing slants outwardly,so that when the bowl is in motion the staples are forced down or lockedby the centrifugal action. The staples hold the segments firmly inposition, the branches of the staples being in contact with the outeredges of the segments on the respective sides of the wings. The insidestructure of the separator, assembled as above stated, is then placed inthe bowl, the shell of which is provided with ribs 0 which fit innotches 0 in the outer rim of the cone (1 and which rest against theouter edges of the disk segments 'i, and which thus serves to assist inholding the disks in position. The segments when put in position willform frustums or cones cut through by the wings. The disk segments arespaced iv apart by bosses t pressed therein.

When constructed as above described the parts may be made and assembledmuch cheaper than when the disks are made in one piece, the segmentsbeing readily stamped i' CIT out and put in place to form segmentalsections which can then be assembled and put in a bowl.

I claim:

1. A centrifugal separator including a bowl, a'cover thereon, a hollowcone in the bottom of the bowl, distributing pipes communicating withthe interior of the cone and projecting against the cover at their upperends, frusto-conical disks mounted upon the cone, and in the bowl, andthrough which the distributing pipes extend, and fastening devicps onthe pipes, bearing against the upper dis 2. A centrifu 'al separatorincluding a bowl, a cone at t 1e bottom of the bowl, having verticalwings, frustoconical disk segments mounted upon the cone and between thewings, and fastening devices attached between the top of the wings andthe cone and bearingagainst the outer edges of the segments, to hold thesame in place.

3. A centrifugal separator including a bowl, a cone at the bottomthereof and having vertical wings projecting upwardly from the bowl andpipes projecting upwardly from the bowl between the wings, andfrustoconical disk segments located between the Wings and having holesthrough which said pi es extend, and fastenings on the pipes to ho d thesegments in place.

4. A centrifugal separator including a bowl, a cone on the bottomthereof having vertical radial wings projecting upwardly therefrom, theWings having notches at the top, disk segments mounted between thewings, and staples hooked at the top in said notches and connected atthe bottom to the cone and bearing against the outer edges of thesegments to hold the same in position;

In testimony whereof, I aflix my signature in presence of two witnesses.

CHARLES NORDSTROM.
